Testing out NEW things!

Yesterday and today I spent time working with podcasting. I am trying to stay on task with what I learned in class with David Jakes in that I want to use this technology to extend student learning outside of the walls of the classroom. I couldn't recall the name of the program David shared with us in class (Luke demonstrated it for us), so I went with Gcast.com. I telephoned in my comments and with the push of a button, the comments were posted! How easy is that??
It was a tad more complicated than that because I HATE the sound of my voice. ;-) I started over several times and posted and re-posted. One thing about Gcast is I couldn't find a "HELP" link, so I was flying solo. If anyone has done podcasting there, or at a similar site I have a few questions. One is, once someone subscribes to the podcast, can they see ALL of the files, including the errors? It seems they were all showing up in my RSS reader. That could be rather embarassing! ;-)
And I am also looking for any TIPS and TRICKS you may have to share with me regarding podcasting.
